Why Tangential Cambridge? Well, for many reasons! First of all, we’ll roam and meander on our tours, exploring links and allusions and often going off at tangents, which is much more fun than sticking to a single track. Secondly, it’s a reference to an iconic Cambridge site (see the picture – courtesy of Wikipedia). Also, it’s a mathematical concept close to my heart. And, finally, it somewhat resembles my own name, Tanya!
